- Description:
- A combination of horizontal dial and gnomonic projection dial. The dial is about 2 x 3 feet made of DuPont Corian sitting upon a simple wood pedestal. A small horizontal dial about 8 inches in diameter with a triangular brass gnomon tells Daylight Saving Time using Roman numerals. Then a larger gnomonic dial is inscribed on the remaining surface, telling time from the shadow of the tip of the triangular gnomon. The gnomonic dial has hourly analemmas,telling time using Arabic numbers in Standard Time. Both dial lines are offset for the longitude of 70 degrees west. The gnomonic dial has declination lines for each month. A small analemma on the meridian has the letters of the months, indicating how to read the hourly analemmas depending upon the date. The dial is built to be read from the north, so the user's shadow does not interfere.
